At RGL we recognise that the protection of the environment is integral and fundamental to everything our business does. We are aware of the reliance our day-to-day jetting operations have on fuel, water usage and the environment, and continually drive innovations to reduce this impact.
A key part of this effort is to ensure that the equipment we choose, and use is regularly maintained and constantly monitored thus ensuring operations run at maximum efficiency with a minimised environmental footprint.
To date we have achieved notable efficiency improvements through the redesign of the jets and nozzles we use which has the knock-on effect of reducing fuel usage and machine up-time.
reduction in water usage using UHP vs. HP
reduction in diesel consumption when cutting steel using two nozzles.

RGL are committed to driving environmental performance improvements through our Integrated Management System by:
10 years ago our Hydrodemolition pumps operated at 1000 bar of pressure and used approx. 110 - 230 litres of water per minute.
Our modern UHP machines, coupled with our bespoke jetting equipment use a mere 27 litres per minute at 2,800 bar of pressure. To put this in perspective of speed, the older pumps were shooting water at 970mph and our new ones manage a staggering 1,650mph (over twice the speed of sound).
In short, our investment in technology allows us to use less than 25% of the water previously used, whilst doubling its speed which is essential when there a potable water supply is limited e.g. offshore or at a remote location.
Another water saving technology is the re-design of our cold cutting nozzles to facilitate two of them being powered by one UHP pump.
Previously two pumps were required. When a two nozzle cold cutting operation is required this refined technology reduces the water consumption from 30lpm (litres per minute) down to 22lpm and diesel consumption could be reduced by 45% whilst maintaining the same cutting performance on tank floors and walls.
The removal and disposal of old, unwanted or deteriorating concrete has the potential to harm health through silicosis and other respiratory diseases, as well as being a strong alkaline which can have a negative effect on the environment.
We take the disposal of our wastewater very seriously and approach the process in 5 principle stages:
Throughout the process, water samples are regularly taken to double check that it is within specified PH levels before discharge. Once the wastewater is pH balanced and suspended solids have been significantly reduced it is ready for environmentally friendly disposal.
RGL is regularly audited on our compliance with our ISO accreditation. We also maintain certifications for our work with industry leading bodies, including:
